Summarize Within 999999

I am trying to do a very basic summarize within function using hex bin polygons and around 40,000 points. The tool fails with a generic 999999 error which leaves me completely baffled with no direction to troubleshoot. Both data sources are wgs84 and are sitting in the same gdb. I tried to keep it as simple as possible and have it summarizing 0 or 1 field at most. Any ideas on how I can troubleshoot? Thanks.

Well I am at a loss on this one. I came in fresh in the morning with the map still open. Took a look at some properties of the hex polygon layer and changed some of the symbology. Decided to try the summarize within tool again and it just worked. I guess I will chalk that up to some buggy behavior in the application.

I used the Generate Tessellation tool to create 100 sq mile hex polygons covering the entire US. Then I use the Summarize Within (Analysis Tools) tool with that layer and a layer of points, which fails with a generic error. I did try the summarize within tool utilizing the same point layer but a different polygon layer and it worked. Seems like it doesn't like my hex polygons for some reason but I can't seem to pinpoint why. Just simple polygons with the same spatial reference as the layer that works.

Interesting... I haven't tried anything in geographic coordinates and I am wondering how it makes the hexagons with a predetermined area in planar units... could be a bug, but I would try projecting everything to Albers (for U.S.) and see if it has to do with that. Otherwise, you might want to report it.
